The importance of preventing hypothermia in the perioperative period cannot be overemphasised. The use of active warming devices is advocated and practised widely. The forced-air warming (FAW) blanket is currently a popular modality. The BARRIER® EasyWarm® (Mölnlycke Healthcare, Belrose, Australia) self-heating blanket, which does not require a power unit, has been proposed as an easy-to-use alternative to the FAW blanket. We conducted a single-centre, randomized controlled trial to compare the efficacy of the EasyWarm® self-heating blanket to the Cocoon blanket (Care Essentials, North Geelong, Australia), a conventional FAW blanket, in preventing intraoperative hypothermia. Forty patients undergoing elective surgery under general anaesthesia lasting >1 h were randomized in a 1:1 ratio. Prewarming was not allowed; 39 patients were analysed (19 EasyWarm® group and 20 Cocoon blanket group). There was no statistically significant difference between the two groups with regard to the mean (±standard deviation) final nasopharyngeal temperature (35.89 ± 0.82 °C versus 35.74 ± 0.77 °C; P = 0.72 in the Cocoon and EasyWarm® blanket groups, respectively). Similarly, the difference between average temperatures at 1, 2 and 3 h was not statistically significant. We found the EasyWarm® blanket to be as effective as the Cocoon FAW blanket in preventing intraoperative hypothermia. Due to its ease of use, the EasyWarm® blanket may have an additional benefit in preoperative warming of patients.
围手术期预防体温过低的重要性再怎么强调也不为过。提倡并广泛应用主动升温设备。强制空气升温（FAW）毯目前是一种常用的方式。已有人提出，无需电源装置的BARRIER® EasyWarm®（莫利医学，澳大利亚贝罗斯）自热毯是一种易于使用的FAW毯替代物。我们开展了一项单中心随机对照试验，比较EasyWarm®自热毯与Cocoon毯（Care Essentials，澳大利亚北吉朗）（一种传统的FAW毯）预防术中体温过低的效果。40例接受持续时间>1小时全身麻醉的择期手术患者按1:1比例随机分组。不允许进行预升温；分析了39例患者（19例在EasyWarm®组，20例在Cocoon毯组）。两组的平均（±标准差）最终鼻咽温度无统计学显著差异（Cocoon毯组和EasyWarm®毯组分别为35.89±0.82℃和35.74±0.77℃；P = 0.72）。同样，1、2和3小时时的平均温度差异也无统计学显著性。我们发现EasyWarm®毯在预防术中体温过低方面与Cocoon FAW毯效果相当。由于其使用方便，EasyWarm®毯在患者术前升温方面可能还有额外益处。
